Soligenix Advances Treatment for Rare Skin Cancer with Promising HyBryte Therapy

Soligenix Inc. (NASDAQ: SNGX) is making significant strides in the treatment of cutaneous T-cell lymphoma (CTCL), a rare and complex group of skin cancers affecting approximately 3,000 new patients annually in the United States. The company's lead product candidate, HyBryte™, a novel photodynamic therapy, has shown promising results in clinical trials, potentially offering new hope for the estimated 20,000-30,000 individuals living with this chronic, incurable disease.

HyBryte utilizes synthetic hypericin in combination with safe, visible light to target and destroy diseased T-cells. The therapy's unique mechanism of action involves the application of a topical ointment followed by light activation, which creates oxygen radicals that cause cellular toxicity in affected cells. This approach has demonstrated efficacy in treating both surface patches and thicker plaques associated with CTCL.

The importance of Soligenix's advancement cannot be overstated. Current treatment options for CTCL often come with significant safety concerns, including black-box warnings. In contrast, HyBryte has shown strong and rapid efficacy with a notably benign safety profile in clinical studies. Dr. Richard Straube, Senior Vice President and Chief Medical Officer of Soligenix, emphasized the treatment's potential to set a new benchmark in CTCL management.

Following successful Phase 3 trials, Soligenix is initiating a second confirmatory Phase 3 study with 80 CTCL patients, aiming to support global marketing approval. This study, set to begin enrollment before year-end with results expected in 2026, represents a critical step towards bringing HyBryte to market. The company's collaboration with key opinion leaders and patient advocacy groups in the CTCL space underscores the potential impact of this treatment on the patient community.

The development of HyBryte aligns with Soligenix's broader mission to address rare diseases and areas of unmet medical need. As the company progresses towards potential commercialization, the implications for CTCL patients and the broader oncology field are significant. If successful, HyBryte could offer a safer, more effective treatment option for a patient population that has long faced limited therapeutic choices.

As Soligenix advances its innovative approach to CTCL treatment, the biopharmaceutical industry watches closely. The success of HyBryte could not only transform the lives of CTCL patients but also pave the way for new approaches in treating other rare cancers, potentially reshaping the landscape of targeted cancer therapies.
